ABSTRACT

An education system, especially for children, includes an audio/visual (A/V) system and a physical activity or exercise device that is in communication with the A/V system. The A/V system is operative only when the physical activity or exercise device is being used, irrespective of any particular level of use thereof. The A/V system is operative to provide only educational content/material when used. The A/V system is in communication with a plurality of educational content/material sources. Various types of physical activity or exerciser devices may be used.

BACKGROUND

[0001] The present U.S. non-provisional patent application hereby claims priority to and/or the benefit of earlier filed and co-pending U.S. provisional patent applications: (a) serial No. 60/306,170, filed Jul. 19, 2001, entitled “Audio-Visual Educational System Activated by Exercise Device Apparatus (sit and go)”; and (b) serial No. 60/312,466, filed Aug. 16, 2001, entitled “Audio-Visual Educational System Activated by Stationary Manual Treadmill”.

FIELD OF THE INVENTION

[0002] The subject invention is concerned with the field of audio-visual educational systems and exercise devices. More specifically, the subject invention is concerned with audio-visual educational systems that are actuated via a physical activity and/or exercise device in order to stimulate and develop the intellectual, emotional, and physical capabilities of children.

DISCUSSION OF THE PRIOR ART

[0003] One of the recurring tasks of raising and educating young children is to ensure that they have access to a sufficient quantity of intellectual, emotional, and physical stimulation for proper overall development. Children display a wide-ranging curiosity about the world around them and frequently become bored if they are not continually motivated with a variety of tasks, learning experiences, and intellectual and physical challenges. Many young children, for example, become bored and restless with schoolwork that fails to sufficiently challenge their mental abilities. Such boredom can lead to physical inactivity and lethargy, which may compound or reinforce the phenomenon.

[0004] Parents, guardians, and teachers have responded with a variety of methods and devices to engage the learning and intellectual faculties of young children, but these efforts frequently fail to deliver the anticipated results. Some approaches underestimate the capacity of a small child for learning new and challenging material while others have largely been directed to a single facet of a child's individuality, such as stimulating either the intellectual or emotional component of personality. A more successful approach would engage the total makeup of the child by providing a comprehensive, interactive experience.

[0005] Numerous designs for exercise devices linked to audio-visual systems, computers and other electronic apparatuses have been provided in the prior art. Even though these designs may be suitable for the specific individual purposes to which they address, they would not be suitable for the purposes of the subject invention as such devices are generally elaborate in design and construction, thereby being cumbersome for a small child to use and operate. Furthermore, such devices typically activate the electronic or audio-visual interface only when the exercise device is operated at a predetermined level of intensity, which can be impediment to use and enjoyment by a small child. Even further, such devices are connected to video games and other non-educational content sources.

[0006] These designs are exemplified by U.S. Pat. No. 5,489,249, “Video Exercise Control System”, issued to Brewer et al., on Feb. 6, 1996; U.S. Pat. No. 5,645,513, “Exercising Apparatus Which Interacts with a Video Game Apparatus During Exercise”, issued to Haydocy et al., on Jul. 8, 1997; U.S. Pat. No. 5,888,172, “Physical Exercise Video System”, issued to Andrus et al., on Mar. 30, 1999; and U.S. Pat. No. 6,142,913, “Dynamic Real Time Exercise Video Apparatus and Method”, issued to Ewert on Nov. 7, 2000.

[0007] What is needed then to overcome the aforementioned disadvantages of previous methods for stimulating and developing the intellectual, emotional, and physical development of young children is the provision of a device or apparatus that combines an audio-visual (AV) instructional and/or educational system and a single unit physical activity device by which the AV system can be activated upon only mere use of the physical activity device.

[0008] As such, it may be appreciated that there is a continuing need for a new and improved apparatus that is simplified in design and construction as appropriate for use by a small child.

[0009] The present invention achieves its intended purposes, objects, and advantages through a new, useful and unobvious combination of method steps and component elements, with the use of a minimum number of functioning parts, at a reasonable cost to manufacture, and by employing only readily available materials.

SUMMARY

[0010] An education system is coupled to and actuated by a physical activity device. In particular, the education system is actuated through mere use of the physical activity device irrespective of attaining a level and/or speed of use. The education system includes audio-visual components that are configured to provide only educational content. The physical activity device is configured for use by a child.

[0011] Described briefly, according to one exemplary embodiment of the subject invention, an apparatus is provided consisting of an audio-visual education system and a stationary treadmill (manual or automatic), as the physical activity device, which, upon use by a child, activates the audio-visual system, thus serving as an incentive for the small to engage in beneficial exercise and intellectual stimulation.

[0012] The audio-visual (A/V) education system and treadmill system is an assembly of components generally comprised of A/V components and appropriate educational content/material source(s), a support assembly, and a treadmill. The support assembly consists of a base, handrail, platform, and cabinet. The A/V components include, at a minimum, a video screen, an amplifier, and a playback device with speakers headphone jack, such as a DVD or videocassette player.

[0013] The base is comprised of two elongate rectangular members that make contact with the floor or ground surface and two vertically-aligned rectangular members disposed at one end thereof. Each vertically aligned rectangular member encloses an aperture or bore. The handrail is similarly comprised of two elongate rectangular members and two vertically aligned rectangular members, which are disposed at one end of the elongate rectangular members. The vertically-aligned rectangular members of the hand rail are disposed in telescoping engagement within the vertically-aligned rectangular members of the base and are maintained in one of several positions or heights with respect to the floor or ground surface by locking pins, which are fitted into cooperating apertures formed within the vertically-aligned rectangular members of the base and handrail.

[0014] The platform is positioned upon the rectangular members of the base at ends thereof opposite to the vertically-aligned rectangular members. The unattached ends of the rectangular members of the handrail are disposed within rectangular indentations formed or fabricated within the front side of the platform member. The cabinet is positioned on the top side of the platform member and houses the A/V devices therein and supports the view screen at a height for optimum viewing.

[0015] The treadmill is constructed of a rectangular exterior frame that encloses and supports a flexible treadmill belt and roller assembly. A first end of the exterior frame is fitted with locking pins that are received by cooperating apertures located within the vertically-aligned rectangular members of the base; a second end of the frame is fitted with floor pads that support the treadmill assembly above a floor or ground surface. As such, the treadmill assembly can be releasably attached to the support assembly and removed as necessary. The roller assembly consists of two elongate rectangular bars that are disposed in parallel relation and connected to each other by a series of axle rods. A cylindrical member is disposed over each axle rod to allow rotation of said cylindrical member. The treadmill belt is wrapped snugly around the cylindrical members. At least one motion sensor is attached to the exterior side of the rectangular bar in order to detect movement of the cylindrical members and treadmill belt. Rotation of the cylindrical members and treadmill belt activates by means of internal wiring, circuitry, and switching the amplifier/playback device and video screen.

[0016] Described briefly, according to another exemplary embodiment of the subject invention, an apparatus is provided consisting of an audio-visual education system and a pedal and/or crank exercise device (manual or automatic) as the physical activity device, which, upon use by the child, activates the audio-visual system.

[0017] The audio-visual (A/V) education system and the pedal/crank exercise device is an assembly of components generally comprised of A/V components and appropriate educational content/material source(s), a support assembly, and an arm crank and leg pedal exerciser with adjustable integral seat. The support assembly is comprised of two rectangular stabilizer members that rest upon a ground surface and receive in central apertures therein the end portions of a rectangular support member. A rectangular platform member is situated upon the top surface of the support member and holds up an amplifier and playback device and video screen.

[0018] The A/V components include, but are not limited to, a display, an amplifier, speakers, and a playback device, each of which comprises conventional consumer electronic equipment, such as a video cassette player, digital video disc (DVD) player, cable box, satellite receiver, or the like, preferably with a jack for headphones. In all cases, the educational images and sounds produced by the playback device or from any other source are fed into the display or video screen for viewing and listening.

[0019] The exercise device consists of a rectangular, horizontal support member that is connected at one end to the support member of the audio-visual system and at a second end to a chair. A vertical member releasably attached to the horizontal support member is fitted with a foot pedal assembly and a hand pedal assembly within reach of a child of any size when the child is positioned in the chair. Internal wiring and circuitry connect the pedal assemblies to the amplifier and playback device so that rotation of either pedal assembly activates the amplifier and playback device and video screen. Such rotation transfers electric power that is initially delivered to a switching device by an electric power cord to the amplifier and playback device and video screen.

[0020] Generally, in use, the overall system is turned on including the A/V system and the physical activity/exercise device, if appropriate. A suitable source of educational content/material is selected and queued as appropriate. Upon a child utilizing the physical activity/exercise device (irrespective of the level of activity), the A/V system will provide the educational content/material (display the video and/or play the audio). As long as the child is using the physical activity/exercise device, the A/V system will provide the educational content/material.

[0021] According to an exemplary manner of use with respect to the exemplary treadmill physical activity device embodiment shown herein, the video screen, the amplifier/receiver, and any other component of the A/V system are turned on, and an appropriate educational content/material disc, cassette and/or the like is inserted into the playback device, or another educational content/material source is selected. A headphone is attached to the headphone jack of the amplifier/receiver device, and is positioned onto the head of a child standing ready on the treadmill. Alternatively, the speakers may be used instead of headphones. As the child walks upon the treadmill, the flexible belt and cylindrical members of the roller assembly rotate, and such rotation or movement is detected by the motion sensor, which activates the amplifier/playback device and video screen.

[0022] According to another exemplary manner of use with respect to the exemplary pedal/crank physical activity device embodiment shown herein, a child is seated within the chair and an educational video cassette, DVD or the like is inserted into the appropriate component and/or playback device. It should be appreciated that other sources of educational content/material may be available and chosen to provide the educational material during use of the physical activity device. Once the child utilizes either pedal/crank assembly, power is switched to the A/V system. At this time, the video screen receives an input signal from the amplifier/receiver and playback device, and an image and accompanying sounds are produced for the child as long as one of the pedal assemblies is rotated.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0041] Referring to FIG. 1, there is depicted a block diagram of an exemplary education system, generally designated 200, in accordance with the principles of the subject invention. The education system 200 is characterized by an adjustable child's physical activity device 202 that is coupled to an A/V system 204. An adjustable child's physical activity device (ACPAD) controller 208 may be (and hence the dashed lines) coupled to the adjustable child's physical activity device 202. Additionally, the education system 206 is preferably, but not necessarily, coupled to external educational content/material sources 206.

[0042] The adjustable child's physical activity device 202 may be any type and/or style of exerciser or the like that is able to be used by a child and configured and/or adjustable for use by a child. The ACPAD controller 202, if provided, is operative to control the physical activity device 202 typically through or in response to input initiated by a user. The user may be a child using the exercise device 202 or a supervisor such as an adult. The adjustable child's physical activity device 202 includes electronic circuitry, logic, and/or the like 203 including a switching device that determines if the adjustable child's physical activity device 202 is being used and sends a signal to the A/V system 204 to operate. It should be appreciated that in accordance with the principles of the subject invention, mere use of the adjustable child's physical activity device 202 provides input to the electronic circuitry/logic of the adjustable child's physical activity device 202 which is operative to provide a start signal to the A/V system 204. The adjustable child's physical activity device 202 is also operative to detect when use thereof has ceased. When use of the adjustable child's physical activity device 202 has ceased, the electronic circuitry/logic 203 of the adjustable child's physical activity device 202 provides a stop signal to the A/V system 204.

[0043] Various schemes may be utilized to provide the stop signal to the A/V system 204, since mere pausing or ceasing use of the physical activity/exercise device for a moment or momentarily should not necessarily cause the A/V system 204 to stop. In one form, the A/V system 204 remains on even during non-use. This period of time should be relatively short since there should be an incentive for increasing stamina. In one form, the time period may be adjustable to accommodate different children. After expiration of the predetermined time period, if non-use continues, the A/V system turns off.

[0044] The A/V system 204 is in communication with educational content/material sources generally designated 206. Such sources may be a database or storage 220, cable television 222, the Internet 224, and/or satellite television 226. It should be appreciated that the A/V system 204 may not necessarily be in communication with each educational content/material source such as shown. As well, other education content/material sources not shown may be used that are not shown. In any case, each educational content/material source provides educational content/material suitable for children to the A/V system 204 as appropriate.

[0045] Referring now to FIG. 2 and FIG. 3 wherein there is illustrated a typical embodiment of the audio-visual (A/V or A-V) education system 200 having an A/V system 204 activated by a physical activity/exercise device 202 that is here, an exemplary stationary and preferably manual treadmill 10. The particular embodiment of the A/V education system 200 is designed to encourage physical exercise and intellectual stimulation of children by providing a device wherein a child of any stature, and/or mental and physical ability can view and listen to various recorded educational media, such as educational digital video discs (DVD) and videocassettes, and/or various broadcast educational media, such as satellite programming, cable programming, terrestrial programming and the like by merely using the stationary manual treadmill 10. The treadmill 10 activates operation of the media playback devices (A/V system) only upon use and operation of the treadmill 10, thereby providing an incentive for a child to engage in physical exercise of sufficient duration.

[0046] The audio-visual education system is generally comprised of a support assembly 12 for various A/V components and a treadmill 14, which is releasably attached to the support assembly 12. The support assembly 12 consists of a housing member 16, base 18, and hand rail 20. The housing member 16 is further comprised of a platform member 22 and a cabinet 24. The platform member 22 is fabricated of a two lateral side members 26 and a top side member 28, which is connected at opposing ends to a lateral side member 26. A series of rectangular indentations 30 is formed into the outer corners of the lateral side members 26. An aperture 32 is fabricated into a longer side wall of each indentation 30.

[0047] The cabinet 24 is positioned onto the top side member 28 of the platform member 22 that supports a video screen or displays 34 and houses an amplifier/receiver/playback device 36 such as an integral receiver/DVD or videocassette player. Of course, other components, integral or stand-alone, may be included in the A/V system 204 as desired and/or necessary to provide the educational content/material. The front panel of the amplifier/receiver/playback device 36 is constructed with at least a disc/tape insert slot 38 and a headphone jack 40. A power cord 42 delivers electric power to the video screen 34 and amplifier/receiver/playback device 36.

[0048] The base 18 is comprised of two elongate rectangular members 44 that make contact with a floor or ground support surface and support the housing member 16 (platform member 22, cabinet 24, etc.) above the floor or ground surface. The rectangular members 44 are disposed in parallel relation and joined in such arrangement by a connecting rectangular member 46. Vertically-aligned rectangular members 48 are affixed to the corners of the rectangular members 44 and connecting rectangular member 46 and extend upward for some distance with upward in this disclosure defined as extending away from the floor or ground surface. Each vertically-aligned rectangular member 48 encloses an aperture or bore for receipt of the hand rail 20 at a specific position or height with the position or height secured by means a locking pin 50 extending through an aperture formed in each vertically-aligned rectangular member 48 and portion of the hand rail 20.

[0049] The handrail 20 consists of two elongate rectangular members 52 disposed in parallel relation and maintained therein by a connecting rectangular member 54. Vertically-aligned rectangular members 56 are attached to the corners of the rectangular members 52, 54 and extend downward for some distance. The vertically-aligned rectangular members 58 are fabricated with a series of apertures 58, which receive the locking pins 50 extending through a cooperating aperture of the vertically-aligned rectangular members 48 of the base 18. The vertically-aligned rectangular members 58 are disposed in telescoping engagement within the apertures or bores of the vertically-aligned rectangular members 48 of the base 18 in order to permit the hand rail 20 to be adjusted to various heights above the floor or ground surface for accommodation of various users of the invention 10.

[0050] Once an optimum position height has been chosen, the locking pins 50 are thus placed within cooperating apertures of the vertically-aligned rectangular members 48, 56, and the ends of the rectangular members 52 of the hand rail 20 opposite to the ends attached to the rectangular members 54, 56 are fitted into a corresponding indentation 30 of the platform member 22 and secured therein by a locking pin 60, which is inserted into the aperture 32 fabricated into the side wall of the indentation 30. The base 18, hand rail 20, platform member 22, and cabinet 24 are manufactured of material that is lightweight, durable, economical to acquire and manufacture, and attractive in appearance, such as various plastics, rubber materials, various composite materials, and the like.

[0051] The treadmill 14, which is releasably attached to the base 18 between the vertically-aligned rectangular members 48 and onto the connecting rectangular member 46, is fabricated of a rectangular exterior housing 62, flexible walking rubber mat or belt 64, and floor pads 66. The floor pads 66 support the treadmill 14 at a height above the floor or support surface commensurate with that of the connecting rectangular member 46 and in parallel disposition to said floor or support surface. As shown in FIG. 3 in phantom line, the treadmill 14 encloses a roller assembly 68, which supports the walking rubber belt 64 and permits said belt 64 to rotate in a continuous loop.

[0052] In FIG. 4, the treadmill 14 is illustrated as detached from the support assembly 12 and aligned for attachment thereto. Locking pins 70 are attached in telescoping engagement to the exterior housing 62 of the treadmill 14 and are received by cooperating apertures 72 formed into the vertically-aligned rectangular members 48 of the base 18 once the treadmill 14 is positioned thereon.

[0053] Referring to FIG. 5, therein illustrated is the roller assembly 68, which is fabricated as a unit that can be inserted into and removed from the exterior housing 62 of the treadmill 14. The roller assembly 68 is comprised of two narrow, elongate rectangular bars 74 that are manufactured of lightweight, rigid material, such as various metals or composite materials, a series of axle 76 rods, and cylindrical members 78. Each axle 76 rod is attached at opposing ends to apertures formed within the rectangular bars 74 and supports in rotating engagement a cylindrical member 78. The walking rubber belt 64 is secured in snug engagement in a continuous loop around the cylindrical members 78. As the belt 64 is urged in a specific direction by a user's walking upon it, the belt 64 rotates the cylindrical members 78 around cooperating axle 76 rods. A motion sensor 80 attached to a rectangular bar 74 detects the rotation of the cylindrical members 78 and transmits a signal via internal wiring, circuitry, and switching of the type well known in prior art and design to the video screen 34 and amplifier/playback device 36, thereby activating said components 34, 36 upon use of the treadmill 14.

[0054] During use, the video screen 34 and amplifier/playback device 36 are turned on, and an appropriate educational content/material source is selected. This maybe a disc or cassette is inserted into the slot 38 of the amplifier/playback device 36 selection of a television channel, or the like. A headphone, which is attached to the headphone jack 40, is positioned onto the head of a child standing ready on the treadmill 14. As the child walks upon the treadmill 14, the flexible walking rubber belt 64 and cylindrical members 78 of the roller assembly 68 rotate, and such rotation or movement is detected by the motion sensor 80, which activates the amplifier/playback device 36 and video screen 34 as referenced previously.

[0055] Referring now to FIG. 6, there is shown an alternative embodiment of the stationary treadmill 10. In this embodiment, the treadmill 10 essentially remains the same as the treadmill of FIGS. 2-5 with the addition of adjustable handrails 250 and 252 and a treadmill controller 270 that allows the treadmill 10 to be automatic as well as provide various information or data regarding the treadmill 10 and/or the child using the treadmill. Particularly, in this embodiment, a first handrail 250 extends from the rail 54 and is adjustably situated in a support 254. The handrail 250 includes adjustment holes that cooperate with holes in the support 254 that allow the handrail 250 to be adjustable along with the rails 52 and 54. A pin 256 holds the handrail 250 within the support 254. A second handrail 252 extends from the rail 54 and is adjustably situated in a support 258. The handrail 252 includes adjustment holes that cooperate with holes in the support 258 that allow the handrail 252 to be adjustable along with the rails 52 and 54. A pin 260 holds the handrail 252 within the support 258. Such adjustability in height allows accommodation for children of different heights.

[0056] The treadmill 10 of FIG. 6 also includes a controller 270 that is operative to control the speed of the treads 64, preferably gradually from stop (no motion) to about two (2) miles per hour. Of course, the controller 270 may be operative to control the treads 64 from stop up to any speed desired. However, since the subject invention is for children, the upper speed limit should not too great. The controller 270 may also provide programs of various speeds such as workout routines. The controller 270 further provides time measurement and other statistical data regarding the user such as calories burned, heart rate, and the like. The controller 270 includes an input pad 272 and a display 274. The input pad 272 accepts user input regarding the various parameters of the treadmill. The display 274 provides visual output as appropriate.

A flat monitor video screen 136, positioned on top of the amplifier/receiver/playback device 128, is connected to the device 128 for receipt of an input A/V signal and electric power. The amplifier/receiver/playback device 128 incorporates consumer electronic technology that is well known in prior art and design and may consist of a videocassette playback unit, digital video disc (DVD) playback unit, and the like. The prerecorded cassettes or DVDs would contain content that stimulates the imagination, curiosity, and development of young children, preferably travel journeys to various places and locations around the world by different modes of travel. Other educational content/material may be played during use.

[0060] The exercise device 114 component is comprised of an elongate, rectangular support member 138, exercise assembly 140, and chair assembly 142. The support member 138 is attached at a first end to the support member 116 of the audio-visual system 112 component and at a second end to the chair assembly 142. The support member 138 is fabricated with a series of apertures 144 along opposing side walls thereof. The exercise assembly 140, which is attached onto the top side wall of the support member 138 in perpendicular relation thereto, is comprised of a vertical member 146 and horizontal member 148. A foot pedal assembly 150 is disposed in rotating engagement within the vertical member 146. Apertures 152 formed within the vertical member 146 permit the foot pedal assembly 150 to be positioned to accommodate various users. Similarly, a hand pedal assembly 154 is secured within the horizontal member 148 with positioning therein to accommodate various users permitted by a series of apertures 56 formed within said horizontal member 148.

[0061] The foot pedal assembly 150 and the hand pedal or crank assemblies 154 are preferably adjustable with respect to resistance in turning the assemblies. Such resistance may be manually adjustable or may be automatically adjustable via a controller or the like. Such adjustable resistance aids in progressive strength building of the child.

[0062] The chair assembly 142 consists of a chair 158, cylindrical support member 160 with adjustment apertures 162, and a disc-shaped base 164. The cylindrical support member 160 is attached directly to one end of the elongate, rectangular support member 138.

[0063] A switching device and a network of wiring and circuitry 203 are disposed within the interior spaces of the support member 116, platform member 122, elongate, rectangular support member 138, and vertical 146 and horizontal 148 members linking the foot 152 and hand 154 pedal assemblies to the amplifier/playback device 128. Electrical power is delivered by the power cord 134 to a switching device. During non-use of the pedal assemblies 150, 154, the switching device prevents electrical power from being delivered directly to the amplifier/playback device 128 and video screen 136. Once the foot 150 and hand 154 pedal assembly, either individually or together, is rotated, the switch opens and allows electrical power to be transmitted along the wiring and circuitry for ultimate delivery to the amplifier/playback device 128 and video screen 136. In this manner, a child can gain access to the audio/visual content of the invention 110 only by engaging in physical activity, i.e. rotating the foot 152 and hand 154 pedal assemblies either separately or in unison, thus experiencing an interactive learning experience that engages, stimulates, and develops simultaneously the intellectual, emotional, and physical capabilities of the child.

[0064] Referring to FIG. 9, there is depicted a flowchart, generally designated 300, of an exemplary manner of operation of the subject invention. Particularly, in step 302, the system is powered up. Powering up the system includes turning on the A/V system 204 and the physical activity device if appropriate. Turning on the A/V system 204 does not mean playing educational content/material. In step 304 educational content/material is selected and/or its source is selected. At this point, the A/V system 204 is ready to play the educational content/material upon use of the physical activity device 202.

[0065] In step 306, the child is allowed to begin use of the physical activity device 202. In step 308, it is ascertained whether the physical activity device 202 is being used. If the physical activity device 202 is being used (Yes) then in step 310, the A/V system 204 is turned on and plays the educational content. The system keeps checking to see if the physical activity device 202 is being used. If the physical activity device 202 is not being used (No), then the A/V system 204 is turned off (i.e. the educational content/material is no longer played, step 312.
